JOHN G. F. GROTE, OF CINCINNATI, OHIO.

IMPROVED SPRING-MATTRESS.

Specification forming part of Letters Patent No. l 2,368, dated April19, 1864.

To a/ZZ whom t may concern:

Be it known that I, JOHN G. F. GROTE, of Cincinnati, Hamilton county,Ohio, have invented a new and useful Improvement in Spring'Mattresses;and I do hereby declare the following to be full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making part of this specification.

My improvement relates to the class of spring-mattresses which areprovided with an elevated portion at one end, called a headrest-,7intended to dispense with a separate bolster; and my present inventionconsists of such an arrangement, adaptation, and construction ot' theyielding and supporting parts a; to avoid the `defects andinconveniences Which have hitherto rendered such mattresses practicallyuseless.

Figure 1 is a longitudinal section of my improved mattress. Fig. 2 is atop view of the same without the ticking. Fig. 3 represents my yieldinghead frame.

I provide a wooden frame, consisting of head and foot rails A and B,side rails, C and C', bottom cross-rails, D, and atop cross-rail, E.

rlhe body-springs F rest upon and are supported by the bottomcross-rails, D.

The tops ofthe body-sprin gs F are all 4connectcd together and securedto the frame by means of a net-work of cords, G G', and are furthersecured by lneans of the longitudinal uords,whicl1, extending from thetop rail,A, to the bottom one, B, are attached to the middle of thesprings F.

H is a band formed of stout webbing, supported partly upon the cord-workG and partly by attachment of its ends to the side rails, G and C', ofthe frame. Supported upon and attached to the upper cross-rail, E, is arange of slender springs, I, which constitute the extreme tier at thehead end of the mattress. A range of springs, I', of similar strength,attached to and supported by the band H, serves to maintain theconvexity of that part of the head-rest intended to fit into the hollowof the neck.

Midway between the two ranges of springs I and l is a range of springs,J, intermedid The springs I, l', and J, belonging to the head-rest, areall retained at their proper relative positions while yielding freely toany pressure by their connection by means of cords G, attached to anelevated and yieldingheadframe, K, bowed or rounded upward to correspondwith the con veXity of the bolster.

Theindependent system of yielding and sustaining parts which go to makeup the headrest enables the body 7 to be depressed with' out draggingthe headrest out of shape or lessening its convexity, my form dilieringin this respect from the common elevated head-rests, which are liable toassume the form of inclined planes, having the eXtreme head or top edgetoo much elevated and too unyielding, and the part which should lit intothe hollow of the neck too much depressed.

The head end of my frame may be partitioned oft' into a box, L, having alid, M, secured by a lock and key or other fastening.

It will be seen that my arrangement opposesno slat or other unyieldingobject to the neck or shoulders of the occupant, as is too often thecase in mattresses ot' this class.

I claim herein as new and of my inventionl. The arrangement of frame A BO C D E, body-springs F, cording Gr G G, band II, yieldin g head-frameK, and graduated springs I, I, and J, the whole being combined andoperating together as set forth.

2. The described combination of head-frame K, cords G, and graduatedsprings I I J, resting partly upon the frame and partly upon theyielding band H.

In testimony of which invention I here unto set my hand.
